uiview - Draw swipe with UIBezierPath in UIImageView -

-

i trying draw in uiimageview..i able draw without problems in uiview using following code:

@implementation drawview {     uibezierpath *path;  }  - (id)initwithcoder:(nscoder *)adecoder  {     if (self = [super initwithcoder:adecoder])     {         [self setmultipletouchenabled:no];          [self setbackgroundcolor:[uicolor whitecolor]];         path = [uibezierpath bezierpath];         [path setlinewidth:2.0];      }     return self; }  - (void)drawrect:(cgrect)rect  {     [[uicolor blackcolor] setstroke];     [path stroke]; }   - (void)touchesbegan:(nsset *)touches withevent:(uievent *)event {     uitouch *touch = [touches anyobject];     cgpoint p = [touch locationinview:self];     [path movetopoint:p]; }  - (void)touchesmoved:(nsset *)touches withevent:(uievent *)event {     uitouch *touch = [touches anyobject];     cgpoint p = [touch locationinview:self];     [path addlinetopoint:p]; // (4)     [self setneedsdisplay]; }  - (void)touchesended:(nsset *)touches withevent:(uievent *)event {     [self touchesmoved:touches withevent:event]; }  - (void)touchescancelled:(nsset *)touches withevent:(uievent *)event {     [self touchesended:touches withevent:event]; }

this skips imageview.. need opposite. wanna draw in uiimageview , skip uiview.. how can that? in advance..

enter image description here

the drawing surface needs parent in hierarchy of view set. way can draw on parent view, while image lies underneath.

-main view --drawing view ---uiimageview

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
